How the Acoustic Envelope Detector works
In response to requests from both university and commercial research departments, Stable Micro Systems developed a method of measuring the acoustic energy release during a physical test.
The acoustic system, which utilises a microphone and pre-amplifier from Danish sound and vibration experts Brüel & Kjær, has high sensitivity to the frequencies emitted by brittle products but has low sensitivity to mechanical noise emitted by the Texture Analyser.
The system contains all the necessary components for connection to a TA.XTplus Texture Analyser, which will generate synchronised force, and sound profiles for individual tests to provide the "4th dimension in texture analysis".
